Study On The Improvement Of Diesel Locomotive Assembly Site In Q Company

Today,when China's economic development slows down and economic problems are gradually revealed,companies with operational difficulties have to re-develop their development strategies.The railway locomotive industry is no exception.Thus,industrial engineering and lean production,widely praised by today's society,provide a good choice for companies that are difficult to develop,it is also an inevitable choice to improve the company's overall competitiveness.In this paper,the use of industrial engineering and lean production methods in the "5S" management,5W1 H technology,ECRS principles,program analysis,operation analysis,work measurementand production line balance,applied to the diesel locomotive assembly site improvement activities.The combination of on-site management and industrial engineering and lean manufacturing technology not only improves the quality control of on-site products,reduces the number of quality problems,improves the profitability of the company,but also reduces the waste of the field and reduces the company's Operating costs,can also improve the company's brand image,increase the company's intangible assets.The contents of the paper can be summarized as follows.1.Introduce the background of the locomotive industry,and the necessity to introduce industrial engineering and lean manufacturing technology into the field of locomotive quality.This paper discusses the research status and direction of industrial engineering and lean production at home and abroad,and puts forward the theory and method of industrial engineering and lean production used in this paper.2.This paper analyzes the present situation and problems of assembly line of diesel locomotive company,puts forward the improvement plan of on-site management and introduces the implementation process.3.The improvement results show that the introduction of industrial engineering and lean production technology in the locomotive manufacturing industry can improve product quality,labor efficiency,shorten the delivery cycle and enhance the company's profitability and industry competitiveness.
